- There is a lot talk about shrinking populations. People are getting older,
thanks to better medical systems and nutrition; and birthrates are
falling in all developed countries. In China & Japan the population
is already shrinking, Europe and even the US may follow. If we believe
the Cassandras the world is doomed. I beg to differ.
First,
I think a smaller population is a big win for the environment and could
be the answer to global warming, another favorite subject of the
doomsayers. Fewer
people burn less energy - and they emit fewer greenhouse gases. Fewer people
also eat less; therefore the incentive to destroy forests, to gain more
land for farming, becomes weaker and the problem of over-fishing disappears.
A
shrinking population also slows down the trend of turning forests &
meadows into the sprawl: fewer people stops the trend of constructing more and more one-family houses, streets, strip malls, store houses
& parking places. A shrinking population makes the world
greener & cleaner!
A smaller population is also the answer to another doomster alert: "The robots are coming" And: "Automation will destroy our jobs!" (" thehill). Both trends are mostly compensating each other: A falling demand for workers, thanks to automation, compensates a declining supply by shrinking populations.
Industrial Revolution
Machines have been replacing labor for many centuries. In the middle ages wind & water mills already substituted human & animal labor. In the 18th century followed steam power, starting the industrial revolution. In the recent centuries the ongoing automation process has been raising productivity
of labor considerably - and the progress has been accelerating.
Artificial Intelligence (AI) is raising the productivity of labor even even further, reducing the demand for human workers even more. DeepSeek, the newest incarnation of the technological progress, is another step in the ongoing progress to more productivity. Microsoft CEO Satya Nadella claims that Moore´s law is "working in hyperdrive" (finance.yahoo ).
And there is more: science is making exponential advancements in the field of
robotics and artificial intelligence and will support the economy and the
labor markets in the coming decades.
Less Work, More Income
Today even farmers are using robots, for instance for
harvesting strawberries or milking cows (wikipedia). Drones
are being used in warehouses and yards for inventory management. Robots also help restaurants to deal with the scarcity of labor.
"Domino’s Pizza Inc. is putting in place equipment and technology that
reduce the amount of labor that is required to produce our dough balls", reports time.com. 3D-printers are also replacing workers, even in construction. "A 3D
printer can build the walls of a house in as little as two days versus
weeks or months with traditional construction materials" notices today.com.
A study by economists John G. Fernald and Charles I. Jones from Stanford & the Federal Reserve Bank of San
Francisco claims that "it becomes possible to replace more
and more of the labor tasks with capital" (robinhanson ). Fernald & Jones define capital as physical capital
(machines including robots & computers), plus human
capital (knowledge & skills) plus discovery of new ideas (inventions
like computer, internet etc.). According to them "artificial intelligence
and machine learning could allow computers and robots to increasingly
replace labor in the production function for goods", meaning that the
society can produce more things without increasing hours worked or even
with a shrinking labor force. As a result the growth rate of income per person and the
long-run growth rate (now around 2%) will rise as well: "The possibility
that artificial intelligence will allow machines to replace workers to
some extent could lead to higher growth in the future.
Universal Basic Income
Naive
observers claim that a shrinking population reduces the demand for
goods & services and will destroy many markets and businesses (noahpinion). These pessimists ignore that demand is the number of potential buyers multiplied with the purchasing power per capita. Thanks to the accelerating technological progress the purchasing power per capita is rising and will overcompensate the shrinking number of consumers.
We can learn from history: In England the bubonic plague (1348 Black Death ) reduced the English population by about 30%. As a result the living standard of the survivors climbed! The reduced workforce caused higher salaries and the diminished population lowered the demand for food and cut food prices ( driveby).
I reckon that technological progress leads to:
- rising salaries (for those still working),
- climbing dividend incomes and stock market gains
which will raise the purchasing power of most people - enough to compensate the shrinking number of buyers. Even those who don`t invest in the stock market may participate via pension funds and insurance investments.
The
productivity gains will finally translate into higher tax revenues for
the governments (by taxing company profits, dividends & stock market gains). Some day a much greater part of goods & services
will be produced by robots and other machines. Then fewer people
may work than today and many things will cost less. Then the time could come for an universal basic income, paid to everybody, and financed by productivity gains delivered with automation (driveby ).
